EOS 20D EF-S 10-22mm f3.5-4.5 USM

| As Shot | CA Corrected | As Shot vs Corrected |

As the chromatic aberration for this lens is not a strong function of aperture corrections in ACR are derived for each marked focal length. 

Focal length Red/Cyan Blue/Yellow
10mm -21 +27
12mm -17 +26
14mm -20 +22
17mm -15 +16
20mm -11 +18
22mm -9 +18

Subset ACR sidecar XMP files can be downloaded here.

Real life example at 10mm is shown below, all with standard use neutral sharpening. First the full frame for reference.

 

100% crops from the top of the frame, first with no correction, second after correction in the RAW conversion.

As can be seen the green fringing is greatly reduced. Further refinement is probably possible on an individual frame basis.
